 Sanitary Back Pressure Regulators > Mark 95 Series



CGDM Series The Mark 95 is designed to regulate the upstream pressure to prevent overpressure situations from occurring which could damage valuable equipment or disturb the process itself, such as when downstream demand reduces or stops.

The Mark 95 is specifically intended for clean, bio-pharmaceutical systems where sterile and precision are required. Available with a hard or soft with a variety of diaphragm and seal materials, the Mark 95 is ideally suited for virtually any sterile back pressure application.

THe Mark 95FT has all the features and benefits of the Mark 95, but offers an additional connection to allow straight through flow when the valve is closed. Primarily intended for pump by-pass loops, the FT option reduces space and cost of the associated system.
